A method for preparing a solid electrolyte for an all-solid state battery, may include obtaining a slurry by dispersing a first raw material comprising lithium sulfide; and a second raw material selected from the group consisting of silicon sulfide, phosphorus sulfide, germanium sulfide, boron sulfide, and a combination thereof in a solvent; and drying the slurry.

Method for preparing solid electrolyte and all solid state battery including the same

Disclosed is a method for analyzing a sulfide-based solid electrolyte using computer simulation including connecting, by a user, to a client accessible to a server, inputting information of a sulfide-based solid electrolyte to be analyzed to the client, transmitting, by the client, the information to the server, implementing, by the server, generation of a three-dimensional structure in which anion clusters and lithium ions are disposed, based on the transmitted information, feeding back, by the server, an implementation result to the client, and displaying, by the client, the feedback result. In addition, properties of sulfide-based solid electrolytes, which cannot be observed by experimentation, can be analyzed based on lithium, ion conductivity.
